This is clearly a track, similar to the low angle ones but much higher angle. Only 2/53 agreements but definitely a track!
Sebastian,

I think you're right - I would have flagged it. These low angle types (IDP/ejecta) seem fairly common, but others are not always spotting them. Not IS - but still well worth recording.

I know this is a bad focus movie, but I clicked on the object near the bottom left edge (19/49 aggreements so far). As far as I can tell we have reached the surface at the bottom of focus in this area based on the linear structure just to the right of the 'object'. But the 'object' still isnt in sharp focus and look rather like a hole, just like the calibration tracks. Pity the focus didn't go a bit lower.

What do others think? Anyone found this thing duplicated on the edge of another movie, seeing the movies tend to overlap a bit?

Since they showed us two movies of this kind as their top scoring candidates for further review I started to mark similar fatures - although I personally dont believe these are tracks.

I am also marking inclusions (or what I think are inclusions) because I want to leave the final decision to the stardust team. It is probably OK to leave some work to them :wink:

What is this?

Post by stevems »

I've got a couple of these in My Events list. Movies that have been viewed 150 to 200 times and have <10 agreements.

For example, here's one.

At about 200 microns from the left and 90 microns from the top, there is something coming into focus that looks very much like a track. It's clearest at the lowest focus.

Here's another.

Look about 280 microns from the left and 130 from the top.

Now, I'm not arrogant enough (not quite) to suggest that I'm right and up to 95% of the other dusters are wrong, but what do you think these artefacts might be? Should I be clicking on these when most others aren't? I've viewed about 2000 movies, and have scores >99%, so I know I'm not totally out to lunch.

But is the majority always right?

I've seen a few like this and didn't mark them. The key for me is that we're at the surface of the gel, so it's seems likely to me that it will resolve to a medium inclusion farther down.

Bill,

Certainly looks like a lateral low angle track to me. I've seen a few similar ones posted are below are three candidates for such tracks I've found myself:

http://stardustathome.ssl.berkeley.edu/ ... d=433711V1 Top left 50/204 Passed cut 1, comment "another IDP"
http://stardustathome.ssl.berkeley.edu/ ... d=862370V1 Lower left quadrant 61/183
http://stardustathome.ssl.berkeley.edu/ ... =7559378V1 Two particles far right 6/98

Starbright
Nice catches. Much more subtle effects on these.
Cheers,

BIG lateral track movie

Post by Martino »

This one I would call "Louganis" cause it looks like the track of a diver piercing the water, and about as huge. I'd expect to find him beyond the top of the screen. Also, there is one less digit in the movie number than any of the others I have tagged before or since.

8 clicks out of 38 views so far

(edit) just noticed some with less numbers in the previous post.

Likely such an inclusion like this in My Events list:
Movie 5714462V1 that have got an official comment: 166 / 66 / Not Extraterrestrial / inclusions

You know you have been doing this to long when you post on the wrong thread cause the microscope is taking up your entire desktop. I moved it to the correct thread now. Sorry.

I posted this one in the 'low-angle' track thread also- does anyone else see it?:

I think this is another low angle track, but it's very faint. In any case it was viewed over 200 times before it was clicked.

Here's a reference where to look, click the image to view the FOV.

Another one of those "expect the unexpected" things...

You really need to remember to keep an open mind with this and not just mindlessly look for what's in the training & cal movies.

I have a few neat things that "could" be tracks in my events list that have a score of 5% or less. I agree that anomalies that are obviously not tracks should not be clicked but when in doubt, it would be better to click it so the Stardust Team knows people are finding "something" in it that may be worth a closer look or even just a refocus to eliminate the possibility of it being a track so the movie can be retired.

Movies I didn't dare click...

Post by lpspieler »

....but that could possibly contain low angle tracks.

194079V1
slightly diagonally from top to bottom

6741172V1
slightly diagonally from left to right

1985087V1
the lengthy vertical structure in the middle between center and the right FOV rim

what do you think? Are these just surface features?

I have to disagree on that one.
I see nothing in focus below the surface features. :?:

They are all clearly visible when focussing above surface so whatever there is it is completly above surface.
Further more, any lateral track must be exactly straight at least the second and third aren't.

So my decision not to mark these was correct. I've come across many lengthy surface features but these were the first where I was not 100% sure they were only surface features.
